PDF Print Security in Firefox

[brett75]

I have disabled printing in several PDFs file. I am still able to print the file when I open in the Firefox browser however.

It doesn't appear to print in any other browsers tested. How can I prevent Firefox from printing a PDF file?

Firefox uses its own PDF viewer, not the Adobe Reader plugin; see http://helpx.adobe.com/acrobat/kb/pdf-browser-plugin-configuration.html
